#37 - the sun alone doesnt have the same effect because air doesnt bend light, while water does bend light...the bent light, refraction and the number of eyes that bugs have detracts them...think about looking at a light through a kaleidoscope, bugs wont fly into an area where their vision is affected that much.

it works, it has something to do with the way the light refracts through the bag with water in it, it messes up the bug's vision
